Can any one help.... I have a 03 Durango... that has had blower problems.. the resistor has been replaced two yrs ago and started to have trouble again.

lost high on fan and lost an intermediate speed as well.. so I replaced resistor again yesterday.. still no high though!.. worked for about 3 min and lost fan completely.... So then i purchased a new blower motor and a new resistor...(third one now) and tried that.... still no high speed...

Does anyone have any suggestions?

Thanks!

 

try posting this in the 1st gen section, most of the guys dont get out of there much, so if you post in there you will be much more likely to get an answer

 

The lower speeds are controlled by the resisters and the switch, the high speed is controlled by the switch and a circuit breaker.

 

One word Swich!

Check the grounding.
